What was at stake.
Every hour of exhaust shutdown affects production. The fab released six windows over a year, each a few hours long, and any overrun would trip tools and scrap wafers.
What we did.
Beck Franklin's role: shutdown scheduling and reporting. We advise and measure; the contractor builds.
Hour-by-hour scripts
Each tie-in was scheduled by the hour, with preparation, isolation, cut-in, test and restart.
Readiness gates
Materials, crews and permits were checked at a readiness gate one week before each window.
Live tracking
Progress during each shutdown was tracked live against the script with the fab operations lead.
Lessons applied
After each window, durations were corrected and the next script updated.
What the team delivered.
In a live fab, an overrun is measured in wafers. We scripted every window so there was none.
Shutdown scheduler, Beck Franklin
